"Whether the child's cocoon picked up, whether it looks or sizes, it is exactly the same as the silkworm cocoons we often eat, but there is a neat mouth on both ends.

Ms. Zhang Said, at the beginning, she thought it was a edible silkworm pupae, "I thought who had the child raised silkworms, and did not raise the cocoon after throwing it away."

"He said that this kind of cocoon is likely to be deliberately put in and to prevent some trees and insect pests. Pharmacy, I was frightened at that time, and quickly asked the child to send these silkworm cocoons back. "

Citizens believe that manual release should be publicized

During the process of sending these cocoons back to the original land, Ms. Zhang met a sanitation worker. The other party confirmed that these cocoons were indeed artificially put in artificially and were mainly used to prevent trees and insect pests. Essence

Ms. Zhang said that last month, his son had seen this kind of cocoon on the tree by the road. "At that time, there were other children picked up to play. Everyone thought it was a silkworm pupa. Throw it to the trash. "

Ms. Zhang said that if the cocoon is indeed a biochemical agent, the staff did not publicize it when she was put. If the child picked it up, it would be easy to danger. She believes that even if it is not a pharmacy in these cocoons, it should be publicized to avoid being picked up by citizens or children who are unknown.

Inside the cocoon is the American white moth killer

What are these cocoons?

The reporter learned from the garden management department of Ganjingzi District that these silkworm cocoons are indeed not silkworm pupae, but the natural enemy of American white moth -Zhou's bee. According to the staff, the reason why these "silkworm cocoons" mistakenly believed that the silkworm pupae was considering daily consumption because it was used to incubate Zhou's cocoons that could be edible, but there was only one worm in normal silkworm cocoons. Zhou's cocoon's cocoon, a cocoon cocoon can hatch 2000-5000 bees.

According to the staff, in recent years, the garden management department of Ganjingzi District has repeatedly launched Zhou's bee in parks, streets, and communities with large amounts of white moths in the United States. The cocoon discovered by the citizens on Huitong Street is just put on. After these silkworm cocoons were put on, in two or three days, Zhou's bee will break out from the opening of the cocoon, and then actively find the American white moths that are surrounded by pupae. Then produce eggs in the pupae of the American white moth, grow and develop in the pupae, absorb its nutrition, and eventually eliminate American white moths.

According to reports, the use of Zhou's bee to prevent American white moths is a method of biological control. Compared with traditional chemical prevention, it has three major advantages. First of all, it will not cause environmental pollution, and secondly, it will not kill natural enemies. It will not cause adverse effects on some pests and birds, and it will not enhance biological resistance and significant prevention and treatment effects.

The staff said that after they put these silkworm cocoons, they would publicize them in the main areas. "It is definitely not realistic to publicize on each tree." The staff reminded the general public that Zhou's bee is smaller and there is no bee needle. , Will not attack people, citizens can live with them with confidence. If citizens, especially children, see cocoons hanging on trees, do not touch and remove cocoons to avoid affecting the effect of ecological insects.
